LUMBER DRIER.

Application filed February 24, i923, Serial No. 620,961.

To all whom t may concern.'

Be it known that l, Koscon D. Srrins, aV

citizen of the United States, residing at Norfolk, in the corporation ofthe city of Norfolk and State of Virginia, have invented certain new anduseful lmprovements in Lumber Driers, of which the following is aspecification.

This invention relates to new and novel improvements in lumber dryingapparatus, and is especially designed for the use of operators ofporta-ble saw-mills, who at present have no means of properly curingtheir products except by the use of cuinbersome and expensive steamboilers and pipglhe prime object ofzthe invention is to provide asimple, durable, economical and efficient apparatus adapted for thepurpose of properly drying and curing the products of portable sawmills.

Another object of this invention is to so construct the improvedapparatus that the parts may be readily and easily disconnect ed, movedto a new location as desired and quickly reassembled.

A. further object of the invention 1s to provide means in connectionwith the apparatus, constituting` a sheet metal hood or protector, whichefliciently serves the double purpose, namely, iirst, to deflect anychips, lint, dust, bark or other substances which would be likely tofall on the hot radiator pipes and cause contlagration, second, to moreevenly diffuse the heat rising from the radiator and thus prevent thelumber' nearest above the pipes becoming cracked or checked from theintense heat radiated fromA the pipes.

The foregoing and such other objects as may appear from the ensuingdescription are accomplished by the construction, an rangement, locationand combination of the several parts hereinafter more fully described,illustrated by the accompanying drawings, andparticularly set forth inthe claims appended hereto, l it being' understood that slight changesin the proportions and minor details of the construction maybe.

resorted to without departing` from the spirit or sacricing any of theadvantages of the invention.

iIn the accompanying drawings forming a part of this specication it willbe seen that z- Figure l is a side elevation vof the apparatus embodyingmy invention, with the metal hood or protector removed.

Figure 2 represents a plan partly in section, taken in the plane of thedotted lines 2-2, Fig. l, looking in the direction of the arrows, withthe hood or protector removed.

Figure 3 is a plan taken in the plane of the vdotted lines 3 3, Fig. l,showing the metal hood or protector in full lines and the heat radiatingpipes in dotted lines, looking in' the direction of the arrows, and

Figure a is a cross-section taken in the plane of the dotted lines 1 -e,Fig. 3, locking in the direction of the arrows.

In the embodiment of my invention as illustrated, it will be seen thatthe numeral 5 designates the furnace, the brick wall of which ispreferably about nine inches in thickness, 6 indicates the cast ironfront of the furnace having rearwardly extended iianges 7 formedtherewith at each side thereof, 8 the channel irons or plates, and 9 aplurality of threaded bolts which are passed through the brick work ofthe furnace from side to side, through said anges 7 and the channelirons or plates, the threaded end of each bolt being provided with asecuring nut l0, whereby the said parts are iixedly secured, andthereby'fastening the furnace securely together. The numeral 1lindicates the cast iron furnace fuel feed door, l2 the ash cleanout andbottom draft door, and 13 the furnace damper formed of heavy sheet iron,with a rod lil extending entirely through the walls of the furnace andprovided with a handle l5 at each end of said rod.

lt will be perceived that the inner or rear end 16 of the furnace whichprojects into the drying or curing house, is formed with an arch to it,which is designed to take care of the tar and other waste matter whichformerly had a tendency to clog up the old form of furnace, hence bythis particular formation the flame appears to completely burn andconsume these lary-products, and for the same reason the furnace isdropped below the level of the drying or heat radiat ing pipes, thefront of said furnace being approximately two feet Vbelow the grade, thenumeral 17 designatingV the pit at the front of the furnace for theattendant or operator.

The drying or curing house 18 consists of any suitable light frameportable structure Whichumay be readily removed and reassembled, and itsinterior is provided with a plurality of upright iron columns 19,properly spaced apart, and adapted to fiXedly prises a Y-shaped member22 at its front end', formed of heavy sheet iron with itsV outer endfittedinto the rear end ofthe furnace, each inner end of said member 22being connected to one end of an outwardly and rearwardly inclinedprimary radiating pipe 23, the o'ther end of each of the pipes 23 beingconnected to one end of an elbow member 24, and the other end .of eachelbow member is connected to one end of an inwardly and rearwardlyinclined primary radiating pipe 25, the rear end of each pipe 25 beingfitted to the inner ends of another Y-shaped member 26, the rear end ofsaid member`26 being connected to the exhaust stack 27, formed of heavysheet iron, suitably secured to the rear of the house, and provided witha damper 23, while the secondary radiator pipes 15 are fitted into castiron collars 29,'securely1 riveted to theA pipes 23 and 25, with thesquared ends of each `pipe 15 projecting into the pipes 23 and 25 inorder to receive its proper proportion of heat, and the central radiatorpipe 30 extends from and connects the Y-shaped members 22 and 26, eachend of said pipe 30 being passed through a castV iron collar 31, rivetedto each Y-member, and projects into each member 22 and 26, in order thatthis pipe 30 may receive only its proportion of heat, approximatelyonefourth. In each primary radiator pipe 23 and 25 near its forward endis fitted a suitable damper 32 by which the heat is controlled in theradiating system and shifted to either side of the system by the propermanipulation of these dampers. This entire heat radiating system issuitably supported upon a plurality of channel irons 33 which arefixedly secured in any desirable manner to the vertical iron columns 19.

vIt will be seen that each section of my improved heat radiating systemcomprising the pipes 23, 25, 15 and the elbows 24'are so constructed andconnected together as to be readily interchangeable.

As clearly shown in Fig. 3, it will be seen that my entire heatradiating system is provided with a sheet metal hood or protector v 34,which is liXedly secured to the beams 20,

and extends above and along the entire length of each radiator pipe, insucha manner that the hood will be suspended. directly over, but not incontact with the radiator pipes. The said hood is formed by bending themetal sheets lengthwise, in the center, to an angle of ninety degreesand is rein- -forced or braced by having metal angle brackets 35 rivetedto its lower sides. After being placed. in position the several piecesare bolted or riveted together, thus forming a continuous hood or tentlike structurel over the entire set of radiator pipes. Each hood is sixinches wider than the pipe it covers and the form, when placed inposition, is like a gable roof house, with the eaves extending beyondthepipes on each side thereof.

It will be readily obvious that the metal hood or protector is adaptedto perform a double function, that is, it not only serves to deflect anychips, lint, dust, bark or other substances which would be likely tofall in contact with the hot radiator pipes and thus cause aconflagration, but it also serves to more evenly diffuse the. heatrisingT from the radiator and prevent the lumber nearest above the pipesfrom becomingA cracked or checked from the intense heat emanating fromthe heat radiating system of pipes.

It will also be evident that my construction of drier will readilypermit the apparatus to be quickly disconnected, moved to a newlocation, and quickly reassembled, and that said apparatus is soconstructed as to distribute the heat substantially over the entire areaof the housethus constituting an efiicient means for the purposeintended.
